SAFETY-LAMP.

Specification of Letters Patent.

Patented Nov. 12, 1912.

To all whom t may concern Be it known that I, FRANK A. SATTER, a citizen of the United States, residing at Chili Center, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Safety- Lainps, of which the following is a specification.

The object of this invention is to provide an improved oil burning safety lamp.

A further object of my invention is to provide an oil tank in which the oil is securely inclosed and separated from the wick by which the oil is burned, the oil being fed fro-m said tank to the wick only at the rate at which it is burned.

Another object of my invention is the oil confined' so that if the lamp is upset it cannot flow out of the lamp or on tothe wick at any greater rate of speed than when the lamp is in upright position.

Another object of inyinvention is to interpose between the oil chamber and the wick on which the oil is' burned one or more feeding wicks by which the oil is fed to the wick on which it is burned.

Another object of my invention is to regulate the How of cil from the tank to these feeding wicks, which iow will be increased as the lamp is turned up and will be decreased the lamp is turned down.

These and other objects of my invention will be fully described in illustrated in the drawings in the claims.

In the accompanying drawings, Figure 1 represents a vertical section through the lamp, on the line 1"-1 of Fig. 2. Fig. 2 represents a horizontal section on the line 2 2X of Fig. 1. Fig. 3 is a detail sectional view of the central cylindrical chamber of the lamp, showingthe wicks in a modified arrangement. Fig. t is a sectional view of the central cylindrical chamber ofthe lamp, showing a round wick interposed between the two feed wicks. Fig. 5 is a detail perspective view of the device that regulates the feed of the oil to the feed wicks. Fig. 6 is a perspective view of the device for raising the wick and for raising the valve through which the oil is fed.

In the accompanying drawings, like reference numerals indicate like parts.

the specification, and pointed out In the drawings 1 indicates the base of the to hold .devices or as part of the feed regulating system of the land 11. The opening 12 is opened `lamp having substantially the same shape as is found in tubular lanterns. This base is essentially a hollow shell. Tnclosed within this shell is an oil tank 2 into which the oil is fed through the filler 3, which filler is closed normally by the screw cap 4. Above and below the oil tank 2 are the air chambers 5 and 6, which chambers are connected the passages 7 and 8 that extend through the oil tank. These passages 7 and 8 are preferably tlat tubes having a rectangular cross section, as is illustrated in Fig. 2. Central of the oil tank 2 is the cylindrical tube 9 which connects the upper and lower air chambers 5 and 6. Extending in a complete loop up through the tubes 7 and 8 and down through the central opening 9 are the endless wicks 10 and 11, which wicks are stationary and are not intended to move, and are intended to be used as feeding feed regulating devices, or as lamp.

Through the cylindrical tube 9 near its base are made the openings 12 and 13, through which oil can escape from the oil tank 2 into the cylindrical tube 9, and as fast as it escapes through these openings 12 and 13 the oil is absorbed by the wicks 1g an closed by the collar 14 which encircles the cent-ral tube 9 and which is raised and lowered to open and close the opening 12 by a mechanism which I will now describe.

Mounted in the oil tank is the tube 15 which tube extends through the upper shell of the base of the lamp and through the top of the oil tank and ends near the bottom o-f the oil tank. This tube is open throughout its whole length except where it is closed by the packing material 16 and 17, wrapped around the stem 18 with which it moves. Through this packing material extends the stem 1S which at the top isprovided with a rack 19. On top of the lamp is placed the burner 20 equipped with the ratchet wheels 21 and 22, rigidly connected to the ratchet shaft 23. This ratchet shaft at its outer end has the knurled wheel 211 rigidly fastened thereto, by which the lamp may be turned up or down. Also fastened to this shaft is the meshes with the rack gear wheel 25 which 19, by which the stem 18 is raised or lowered with the wick. Thev over the tube 30.

Mounted in the burner 20 is the wick 34.- on which the oil burns in the burner 20. This wick 34 comes in contact with the wicks 10 and 11 near the top of the oil tank, as shown in Fig. 1. The feeding wicks are held in Contact with the burning wick by means of the cone 35 which is perforated at 36 and 37, through which perforat-ions the wicks 10 and 11 pass. By this cone the feeding wicks may be held in any position against the burning wick.

As shown in F ig. 2, the cone holds the wicks 10 and 11 close together so that the burning wick 34 lies between them and parallel thereto instead of perpendicular thcreto as shown in Fig. 3, and as shown in Fig. -1 the cone holds the wicks l0 and 11 against the round or tubular wick 38, by which the oil is burned in the burner.

It will thus be seen that none of the wicks of the lamp are immersed directly in t-he oil in the oil tank 2, but that oil is fed to the wicks only through openings the size of which may be varied according to thc size of the lamp and the rate at which it consumes oil. These openings and the regulation of the flow of oil through them are adapted to pass the oil on to the wicks only as fast as the burner consumes it, so that there is little or no free oil in the bottom of the lamp or in the space that directly communicates with the burner that can run out of the lamp or into the burner in case the lamp is upset.

I have shown and described endless stationary wicks, but it will be understood that any form of stationary wick that is held in place to absorb t-he oil as it is fed from the oil tank and feed it in turn to the moving wick, comes within the spirit and scope of my invention and is the full mechanical equivalent of the endless wicks described and claimed. The endless wick is made by putting an ordinary long single wick in place and sewing the abutting or overlapping' ends together.

Having thus described my invention, what I claim as new and patentable is as follows:

1. In a safety lamp the combination of a base, an oil tank isolated therein, one or more adjustable openings from said oil tank, stationary wicks mounted in said base adjacent to said openings to absorb the oil that flows through said openings, a burner, a movable wick mounted in said burner making Contact with said stationary wick to absorb the oil therefrom.

2. In a safety lamp the combination of a base, of an oil tank mounted in said base, leaving an air space above and below said oil tank in said base, a plurality of openings through said oil tank connecting the air spaces at the bottom and the top of said base, endless stationary wicks extending around through said openings, a burner stem 18 at its bottom has the cross bar 26 and above this cross bar the stem is perforated or drilled with a hole 27. rl`he stem is preferably a round rod about three-siX l teenths of an inch in diameter, the hole 27 being preferably about an eighth of an inch in diameter. The stem 18 has a ring cut therein around the rod both above and below the hole 27 on which the packing material 16 and 17 is wound and by which it is held in place by the rod 18 with which rod it moves up and down in the tube 15. rl`he tube 15 is perforated at 28 and 29. From the perforation 29 leads a tube 30 which extends to the central cylindrical tube 9, to which it is connected so as to encircle the hole 13 so that no oil can pass through the hole 13 except such as passes through the tube 30. Then the stem 18 is in the position shown in Fig. 1 the oil can pass through the openings 28, 27 and 29 into the tube 30 and through the opening 13 into the tube 9 on to the wick 11. The oil cannot pass up through the tube 15 from the bottom for the packingmaterial 17 shuts olf the oil from passing inl that direction. Neither can the oil rise in the tube 15 through the opening 27 as the packing material 16 prevents it. The tubes 30 and 15 are connected together so as to completely surround the opening 29 in the tube 15. v

The stem 18 carries. a cross'bar lower end, on one end of which is carried the collar 14 which encircles the inner tube 9. This collar is cut away at 31 where'it passes This collar closes the opening 12 but does not close the opening 13, the feed of oil through which opening 13 is cont-rolled through the opening 27 and the stem 18.

`In the bottom of the oil tank 2 is a vent opening 32 having an inverted cone shape. On the out-turned end of the cross bar 26 is a cone shaped plug 33 adapted to work out of and into the vent opening 32 as the stem 18 is raised and lowered. When the stem 18 is raised the vent opening 32 is opened and air can bubble up into the oil tank through this opening as the oil flows out through the tube 30 and thro-ugh the opening 12. In this way the flow of oil from the oil tank on to the feed wicks 10 and 11 'is regulated.

If desired the opening 12 may be dispensed with or closed up, in which case the collar 14 may be omitted. In this case the oil will vbe fed solely through the tube 30 and the opening 13 in the manner above described. The air space 6 at the bottom of the tank will be filled with wool or cotton which will absorb any excess of oil that may escape into the air chamber, by which such oil will be fed to the wick 10, so that both wicks 10 and 11 will receive a supply of oil through the tube 30.
